This invention relates tor pipe couplings, and has as its obyect the provision of a coupling intended, primarily, for use connec-r tion with the radiator havingl inlet .and outlet passages for the heating medium through hollow supporting legs,vsucha radiator be- 5 means whereby the same may serve also asv an escutcheon plate to engage the floor or other supportaround an opening through which the piping extends.

IA`furth er object of v`the vinvention is to construct the coupling so that the collar will support the radiator, or other plumbing fix-y ture to which the. pipe line is connected, by the coupling. y

Anadditional object of the invention resides in the provision of means located, ypreferably, upon thecollar for quickly indicating leakage at the coupling. Referring to the drawings, wherein there is shown a preferred embodiment ofv the inventionz- Y e Fig. l is an elevational view of a radiator showing theinvention applied thereto,

Fig. 2 is a vertical section of the coupling "secured in position,

Fig.. 3 is a horizontal-'section on the line 3.-3 of Fig. 2 and Fig. 4 is ahorizontal section on theline 4 4 of Fig. 2. y

Referring to the drawings forl amore def-l tailed description, indicates a radiator formed of a plurality of sections,.the end.

sections having hollow legs 11' throughl which 'the heatmgmedium, such as steam or water, may enter and leave the radiator.

One of the couplings constituting the pres# ent invention serves to connect each leg `with a pipe section 1st. The coupling comprises ac-ollar 15 internallythreaded, as at 16, and havinga projection '17, in the present instance a flange, extending Vinto its bore. A

connection member 18 hasav circumferential projection, for example shown as a flange ,149,'abutting the fiange 17 .Within the collar, the connection member being insertible through the lcollar and vhaving threads. 20

adapted to engage threadsh21' Within the opening leading. into the radiator.

' and tted upon the end ofv the pipe section 14, the latter beingthreaded, asat 27, to engage internal7threafds28 Within the connection member 24. f It will be noted that the coupling l'connection members make a yjoint 29y Within the collar 15, the connection memberl 18 having an externally beveled portion 30 fitting within a correspondingly beveled internal seat upon the connection member 24.

The collar'l serves to tighten the joint 29 and is of angularcontour, as indicated in Fig. 3, sothat the same may beturned by suitable tools. .They collar is also provided With ran integral circumferential flange32 which engages the surface of the floor'F, or other suitable support around an', opening F therein, through Which theV pipe `section 14ey and av portion of the couplingv extend. The collar thus serves. as a ycombined coupling collar and an I'escutcheon plate and, additionally, supports the radiator l0 or other plumbing'fixture in connection with which the coupling may be employed. -By forming the fiange integral with the collary the coupling is reinforced, as the,y flange serves to thicken thelwall ofA the collar. When the coupling is employed asa support.Y fora radiator the fiange will receive the Weight of the radiator and there is less danger of the internal threadsvof the collark being strippedthan if the flange were simply secured to the collar. Ifl desired, the under surface of Ithe 'flange "may be slightly concave so thaty the same Will, around its membersare joined by threading the collar 15 upon the connection member 24. As the sol 4 beiioted that While the coupling collar is rotated the joint 29 is inade tight so that the fluid passing through the coupling will not leal( therethrough. As this joint is concealed it will be found desirable to piovide in vthe collar,l preferably on thev saine horizontal plane with the jointi an opening 36 extending through the Wallfot the collar and communicating with the bore thereof. Should there be any leakage at the joint the iiuid will tirst pass through the opening 36, which is the path ot least resistance, and thereby indicate to the fitter the nece 1., toi' givii'ig iturther attention to tlie'tiglitening ot' the coupling. 1t will. is being set up, theu'eight ot the radiator will be carried by the tivo members ot the coupling independently ci the uniting collar and escutcheon plate which will not receive the Weight until `the joint has been completed, and theunder surface ot thecollar bears against the tloori'or other support.l It is, oit course, desirable that the tightening member be freely adjustable, which would not' be possible it the Weightot the radiator or other deviceis cairied by the saine While the joint is being completed. it Will be understood that numerous modiiications may-be made inthe precise construction disclosed and described Without departing from the scope of the invention, which is defined in the following` claims.
